The Picture of Dorian Gray is the only published novel by Oscar Wilde.
The novel tells of a young man named Dorian Gray, the subject of a painting by artist Basil Hallward. Basil is impressed by Dorian's beauty and becomes infatuated with him, believing his beauty is responsible for a new mode in his art. Dorian meets Lord Henry Wotton, a friend of Basil's, and becomes enthralled by Lord Henry's world view. Espousing a new hedonism, Lord Henry suggests the only things worth pursuing in life are beauty and fulfillment of the senses. Realizing that one day his beauty will fade, Dorian (whimsically) expresses a desire to sell his soul to ensure the portrait Basil has painted would age rather than himself. Dorian's wish is fulfilled, plunging him into debauched acts. The portrait serves as a reminder of the effect each act has upon his soul, with each sin displayed as a disfigurement of his form, or through a sign of aging.
The Picture of Dorian Gray is considered a work of classic gothic horror fiction with a strong Faustian theme.
